Why use D-tips?

• Find known problems (pattern failures) Fast!

  Know what’s most likely to be wrong before you even start, and how to test it!
  The fact is, most vehicles have the same problems over and over again. Why spend hours following lengthy trouble trees when you can go straight to the source of the problem with our easy to use search engine. Don’t wait until you have already backed yourself into a corner and spent hours with a problem vehicle. Check for tips on every vehicle before beginning the diagnosis, and you will save countless hours in diagnostic time.
  

• Real world test procedures

Of course if you are a glutton for punishment, you can always go back to the old way of testing "circuit 467 at connector 231 for less than 5 ohms resistance" and then move on to step #26 in the diagnostic tree, "replace with known good part".
